When Harley came out with the upgrade kit to adapt the M8 water pump to replace the OEM style on the 2016 twin cooled I know many of you made the change to the new pump.

Has anyone had the new style pump fail yet?
I am looking at buying a 2016 and I take long trips. I dont want this to be an issue.
Thanks

Four days later and not a single response......I guess that answers that question.

 

No help here my 16 is still on the original pump

 

I did find a thread where dealers consistently say if it fails it is ok to continue riding it to either get home or make it to a dealer even if it is a couple hundred miles away.

I know on a car that would warp the head from the heat and ruin the valve seals.I would like to see a twin cooled head and see how much different it is from the air cooled head. If there is a lot of material there maybe that's accurate..

 

i can tell you there is very little coolant in the head it only flows around the exhaust valve

 

My first pump went out just under 50k almost 80 k now on bike no problems on the updated pump.

 

FWIW.... There have not been a lot of posts on this problem, since the initial surge of problems with the original pump, now that the new pump is out...

Come to think of it, I haven't seen any posts from/about the services that would rewire/fix the old style pumps, now that the new one has come out...

We all know how issues get magnified on the internet... so I guess that can mean the new pump is doing OK....

 

New Style pump last year on 2015....no problems...

 

Still on the original pump...no problems. (2015 Ultra Limited - 17M miles)
